Insion NIR Microspectrometers

A new generation of NIR-Systems by INSION GmbH. A high grade of robustness due to an improved monolithic design, brilliant optical characteristics as well as the small dimensions open up possibilities in various new and also common applications.


Insion offers near-infrared (NIR) optical spectrometers which are based on a self-focusing Echellette diffraction grating in the Rowland configuration. The functional elements of the microspectrometer – entrance slit, reflective grating, deflecting mirror and light traps – are monolithically integrated into a single chip. The microspectrometer chip, lid and enclosure are homogeneously manufactured to a high standard with excellent optical performance characteristics and inter instrument agreement using micro-injection moulding technology.

Product features:
  • No moving parts.
  • Excellent mechanical, optical and thermal stability.
  • Unsurpassed price / performance ratio.
  • Small dimensions.
  • Easy and flexible handling.

The state-of-the-art photo detector facilitates precise measurements in the NIR range in hand held devices and in-line process sensors. The NIR optical spectrometers are based on an InGaAs line scan detector array. For applications where long-term noise reduction is key, thermoelectric cooling of the InGaAs detector is available as an option for all models. The Insion NIR optical spectrometers are currently available in the wavelength range between 900 nm and 2,000 nm. Insion also offers visible, ultraviolet and near near-infrared spectrometers.


Insion´s microspectrometers are available as fibre-connected OEM microspectrometer modules, as OEM spectral sensor systems or as fully housed rugged plug & play kits. The fibre-connected OEM microspectrometer module is a simple module which do not include readout electronics; as a result, it is ideal for integrating into your own system. Alternatively, the OEM spectral sensor system include the module, an electronic platform and software for control and data pre-processing. The fully housed rugged plug & play kit is a great option for end users; it is user-friendly and includes the module, housing, an electronic platform and software for control and data pre-processing.

INSION customers benefit from the high performance of our micro spectrometers in various application fields:

It is integrated in FDA approved medical diagnostics devices using classical in-vitro assays, innovative reagentless approaches down the road to trans-dermal spectral analyzers. Device concepts are including clinical laboratory analyzers, mobile point of care devices and miniaturized hand held devices.

INSION spectrometers are the basis of on-line detection systems in the field of food processing, pharmaceutical production, chemical process control and sorting machines as well as for invisible security markers or for detecting hazardous substances.

Other applications are established in the fields of analytical instrumentation, elemental and environmental analysis, and water analysis as well as colorimetry and irradiance measurements.

The use of the micro spectrometer allows for an amazingly small sampling and detection system at the point of interest. This strategy is minimizing typical sampling errors, like for example the change of the sample constitution between sampling and off-line analytical investigation. Thus, the micro spectrometer grants enhanced specificity and sensitivity.

In addition to significant functional advantages, these applications for decentralized analytics and diagnostics deliver immediate results at minimum cost-per-test.
